The first-generation Honda CR-V has been out of production for more than two decades, yet it still runs in large numbers across export markets, and its front suspension buffer remains a steady wholesale item. When a buyer searches for OE 51722-S10-004, the number usually comes from a dealer parts diagram, an old invoice or a worn part pulled off the strut. The questions behind the search are practical: which vehicles it fits, what the replacement is made of, and where to source it in volume. This page answers them against the specification we supply and the catalogue evidence for this reference.
The part is a compact polyurethane bumper fitted on the front strut, one on each side. It is small and inexpensive, but when it fails the damper and the coil spring take the load it was designed to absorb, so it belongs in every Honda suspension programme.
51722-S10-004 is the Honda reference for the front strut bumper, also listed in dealer catalogues as a jounce bumper or rubber front bump stop. The leading block, 51722, identifies the Honda front spring bumper group; the middle block, S10, points to the model platform the part was introduced on, here the first-generation CR-V; the trailing block marks the design revision. Under our numbering the item is carried as Bonpora No. 4110092, a code that maps one-to-one to the OE reference for quoting, sampling and reordering.
The bumper sits on the damper rod inside the coil spring and stays passive through most of the suspension travel. As the spring approaches full compression, it engages progressively: it limits coil-to-coil contact, protects the damper internals from bottoming damage, and reduces the peak force reaching the strut mount and the body.
Dealer catalogue data lists the position as front, left and right, meaning one bumper per front strut and two per vehicle. The part is sold per piece, most wholesale orders are planned in pairs, and one item code covers both sides of the axle.
The table below lists the specification set we supply against this reference. When comparing quotations, the bore diameter, the body diameter and the elastomer are the lines that decide whether two offers describe the same part.

At 60 mm overall length this is one of the shorter bumpers in the Honda front-spring family, and the 11.9 mm bore must pass over the damper rod with the correct clearance. A substitute with a taller body or a tighter bore either preloads the spring or seats incorrectly, and neither fault is visible from a photograph. Some European catalogues list buffers for this reference at around 59 mm; the difference sits within normal measurement-convention variation, and we hold the part to the 60 mm drawing figure.
The application is the clearest part of the picture, because several North American Honda dealer catalogues list this reference in detail. The vehicle fitment covers the first-generation CR-V, five-door, in LX, EX and SE trims, model years 1997 to 2001, with the 2.0-litre four-cylinder engine and either the 4AT or 5MT transmission, in both 2WD and 4WD versions. In the dealer suspension diagram for the 2001 CR-V LX, the reference appears as the strut bumper, grouped with the damper, the coil spring and the upper mount.
| Source | Application shown | Position note |
|---|---|---|
| Honda dealer catalogues (North America) | CR-V five-door LX / EX / SE, 1997-2001, 2.0L L4, 2WD and 4WD | Front strut, left and right |
| FEBEST fitment guide (HDB-001) | CR-V RD1 / RD2 / RD3, plus Accord CG and CF series, Torneo, Avancier, Ascot Innova | Front axle |
| European aftermarket listings | CR-V I (RD) 1995-2002 and CR-V II (RD_) 2001-2007 appear in some cross lists | Front axle |
Aftermarket cross-reference guides extend the application list beyond the CR-V, adding the Accord CG7/CG8/CG9 saloons of 1999-2002, the Japanese-market Accord CF and Torneo series, the Avancier TA1-TA4 and the Ascot Innova. These cross lists are compiled from shared geometry observed in trade data, and they are useful for distributors serving mixed Honda stock. They should be treated as a search aid rather than a fitment promise: the authoritative route is always the OE number on the old part, checked against the VIN where a doubt remains. For a mixed programme, stock against the dealer-catalogue core and treat the wider list as enquiry-driven.
Buyers searching by number will meet several alternative codes for the same physical part. Knowing which catalogue each code belongs to makes quotations easier to compare.
| Brand | Reference | Catalogue note |
|---|---|---|
| Honda (OE) | 51722-S10-004 | Front strut bumper, CR-V 1997-2001 |
| FEBEST | HDB-001 | Front shock absorber jounce bumper, front axle |
| MAXGEAR | 72-5848 | Suspension rubber buffer, front axle |
| ZZVF | ZVTM017A / ZVTM028A / ZVTM005A | Suspension buffer listings under the same OE |

The original CR-V bumper is a rubber part, and most replacements in the trade are offered either in rubber or in polyurethane. Our item is produced in microcellular polyurethane, and the choice of material is worth a short explanation.
Rubber buffers degrade with age and ozone exposure: they harden, crack on the outer surface and eventually crumble, which is why buffers on vehicles of this generation are frequently found in pieces during spring or damper work. Polyurethane resists compression set and ageing better in most service conditions and keeps a consistent engagement point over a longer service interval.
The bumper is a tuned component: its length, wall thickness and foam density set the engagement point of the last part of the stroke. A like-for-like PU replacement should match the OE envelope, and the quoted stiffness should sit within the range the strut was designed for. Substitutes that are shorter, softer or harder change the behaviour of the axle near full compression, which is felt as harshness or bottoming, so the full dimension set should be confirmed before dispatch.
For distributors, polyurethane versions of classic Honda buffers fill a demand gap: the OE rubber part is not equally available through dealer channels in every market, and independent workshops servicing older CR-Vs increasingly order aftermarket PU stock. The material also suits custom suspension buffers where a customer needs a modified bore, length or hardness.
Workshops usually find the fault during spring, damper or mount work rather than through a dedicated complaint, so a short checklist helps counters sell the part proactively.
Typical findings are a bumper that has collapsed to a fraction of its free height, surface cracks that progress into missing chunks, or a stop that has slid off the damper rod entirely. Drivers may report a knocking over sharp bumps or a harsher ride as the spring starts to reach coil bind. With the wheel removed and the spring compressed, the inspection takes minutes.
Because the buffers wear with mileage, uneven wear between the two front corners is common once one has failed. Replacing both at the same time keeps the axle behaviour symmetric and matches the two-per-vehicle cataloguing, and it shortens the repair visit when the buffers are stocked beside the dust cover and strut mount.
Bonpora supplies this item as part of a dedicated Honda suspension buffer programme, produced on our own tooling and shipped from China directly to distributors, wholesalers and parts platforms.
The bumper is moulded in polyurethane on tooling cut to the OE envelope, with incoming material checks and dimensional sampling during production. Parts are verified for bore, body diameter and free length before packing under the same quality management we apply across our polyurethane bump stop range, and customers can request inspection reports with their shipments.
Standard packing is neutral export packaging, so the goods arrive ready for your own brand or for shelf display. Lead time is 15-30 days depending on order size and season, and the item consolidates easily with other shock absorber components and chassis and suspension parts in a mixed container. A one-year warranty applies under normal service conditions. The same tooling base covers strut bump stops across Honda platforms and extends into Japanese and European chassis applications, so distributors can widen the range from the highest-turning OE numbers outward.
Send the OE number 51722-S10-004, the Bonpora number 4110092, or a photograph of the old part with measurements. If the application is unusual, include the VIN or model year and market so fitment can be checked.
Indicate the quantity, required packing and destination port. Quotations cover unit pricing by volume band, sample arrangements and the delivery window; custom labelling and own-brand packing are handled here.
For new customers we recommend a sample check against the dimensions in the table above before the first bulk release. Production then follows the confirmed drawing, with shipping documents issued against the agreed terms.
Honda dealer catalogues list the reference for the first-generation CR-V, five-door LX, EX and SE trims, model years 1997 to 2001, on the front axle, left and right. Aftermarket cross guides add the Accord CG and CF series, Torneo, Avancier and Ascot Innova. Treat the dealer-catalogue application as the core and confirm wider use by the OE number on the old part.
Two, one per front strut. The stop is sold per piece, but because both corners wear together at this age, ordering in pairs is the usual practice and the natural unit for wholesale pricing.
The drawing size is 11.9 mm bore, 50.2 mm body diameter and 60 mm overall length, moulded in polyurethane. Beyond the standard item, our custom service covers modified bore, length, durometer and colour for volume projects, produced to drawing with samples approved before mass production.
Delivery is 15-30 days from order confirmation depending on quantity, packing is neutral export packaging suitable for own-brand relabelling, and the warranty is one year under normal service conditions. The item ships in mixed containers with other suspension and chassis parts without restriction.
OE 51722-S10-004 is a small item with a dependable demand curve: an ageing SUV population, a two-piece service requirement per repair, and steady replacement cycles. Bonpora supplies it under Bonpora No. 4110092 in polyurethane to the OE envelope, with factory-direct pricing, neutral export packing and 15-30 day delivery. Send your enquiry with the OE number and quantity, and our team will confirm the specification and quote the programme that fits your market.
